Hello guys maybe I can clear things up with the dizzy question. It's the original owner here.
Old dizzy failed (but appears not to be the actual coil) but could be one one the components. Whatever, it's tested as not producing a spark (albeit with the age old leads - sorry)
Rude - thats the one in the box btw
So I sourced this -

It worked but gave me a misfire, not that noticable at low revs but it was there > 3500rpm
The coil in the new dizzy failed again and I had a new coil put in. However the new one lasted even less time and thats when it was mothballed.
Ps - I've tried another cap so it's not just the cap (although it should really be changed) but you might want to try a new rotor arm and the leads of course (not tried)
Pps that is the original cap that's on now - the blueprint ones are rubbish IMO
Ppps the spark plugs are very recent so I would keep them for spares?
Hope helps.
